KNBC (NBC) · Channel 4

Full-power stations are the main licensed broadcasters in a market. They may run the highest power from the tallest towers and are protected from interference, so they set the core of what you can receive.

At 1,000 kW effective radiated power, KNBC runs more power than 79% of full-power TV stations nationwide (median: 273 kW).

Its antenna sits 1,005 m above the average surrounding terrain, higher than 98% of full-power stations. Taller antennas see farther: this one's radio horizon is roughly 89 miles, beyond which the signal fades quickly.

We estimate a fair-or-better signal out to about 99 miles with an outdoor antenna. That area includes 365 cities and towns in our guide with about 20,900,000 residents, as far as Cathedral City, CA (97 miles).

KNBC shares its transmitter site with KVEA (Telemundo), KTTV (Fox), KCOP-TV, KTLA (CW), KJLA and KXLA and 19 more. One antenna aimed at this site picks up all of them.

The nearest other NBC station in our data is KMIR-TV in Palm Springs, CA, 97 miles away. Viewers between the two can sometimes receive both.

NBC is one of the four big commercial broadcast networks. Local NBC affiliates carry the national morning show, evening news and primetime lineup, plus Sunday Night Football and, in Olympic years, the Games.
